XMM observations of the high redshift type-2 QSOs detected in ASCA

We propose to observe two high redshift (z0.67 and z2.35) QSOs, detected in our deep ASCA survey which appear to be obscured in the optical. These may represent the high redshift counterparts of the local obscured Seyfert galaxies and the XMM observations will probe for the first time in detail the nature of this long sought population. In particular we will (1) probe the nature of circumnuclear matter at high redshift using both the Fe line around 6 keV and the neutral column density diagnostics (2) check for possible evolution in the intrinsic powerlaw spectrum similar to that witnessed in highredshift type1 QSOs by Vignali et al.
